OPTICAL FILM LAMINATE WITH A CONTINUOUS WEB OF CUTTING LINES AND MANUFACTURING METHOD AND MANUFACTURING APPARATUS THEREOF

摘要

[PROBLEMS] It is intended to provide an optical film laminate with predefined slit lines for enhancing both product accuracy and manufacturing speed in liquid-crystal display element manufacturing to radically improve manufacturing yield. [MEANS FOR SOLVING PROBLEMS] The present invention provides a continuous web of an optical film laminate with predefined slit lines for use in a continuous manufacturing system by laminating optically functional film sheets to liquid-crystal panels. The optical film laminate comprises an optically functional film having an adhesive layer comprising a defect-free region having a predefined length corresponding to the dimension of a liquid-crystal panel and a defective region having a predefined length different from the defect-free region, defined in a longitudinal direction, based on the detected position of defects, and a carrier film releasably laminated to the adhesive layer, wherein defect-free normal polarizing sheets and a defective polarizing sheets are formed on the carrier film by forming slit lines corresponding to above regions along the transverse direction of the optical film laminate.
